80. The income replacement indemnity of a student contemplated in section 10, of a child contemplated in paragraph 3 of section 11 or of a worker who is a full-time student is(1) $50 per week until 18 years of age;
(2) from 18 years of age, computed on the basis of the gross annual income determined on the basis of the minimum wage then in force; and
(3) from 21 years of age, revised upwards if he proves to the Commission that he could probably have earned a higher gross employment income at the end of the studies being pursued had he not suffered an employment injury.
Notwithstanding subparagraphs 1 and 2 of the first paragraph, the student or child may prove to the Commission that he has earned, during the 12 months preceding the date he became disabled, a gross employment income entailing a higher indemnity and in this case section 65 does not apply in respect of the minimum employment income.
The review made under subparagraph 3 of the first paragraph replaces any review under section 76.
